To all whom it may concern:

Be it known that I, Cmrronn S. GOBY a citizen of the United States, resident oi Cleveland, county of Cuyahoga, and State of Ohio, have invented a new and useful Improvement in Internal-Combustion Engines, of which the following is a specification, the principle of the invention 'bein herein explained and the best mode in w ich I have contemplated applying that principle, so as to distinguish it from other inventions.

means, however, constituting but one of various mechanical forms in vwhich the principle of the invention may be applied.

In said annexed drawingsz'Figure 1 is a front elevation of the engine structure embodying my invention, showing the parts broken away to disclose the interior parts, the lower portion of the frame being broken away. Fig. 2 is a partial end elevation and vertical transverse axial section, upon an enlarged scalc,'of one of the cylinders of the said engine. Fig. 3 is a horizontal section taken upon the plane indicated by line III-III in Fig. 2. Fig. 4 is an elevation of oneof the valves detached from the valve chamber, and Fig. 5 is a horizontal section thereof taken upon the plane indicated by line V-V in Fig. 4. Fig. 6 is an elevation of the interior valve-seat-forming wall of the valve chamber, detached, and Fig. 7 is a transverse section of same taken upon the plane indicated by line VII-VII in Fig. 6.

The frame A of the engine comprises a lower base portion A, consisting of a single casting, together with an upper capping portion A, also consisting of a single casting, and secured to the base portion by means of suitable bolts and nuts a a, by means of which the said base portion may be readily attached or detached, as will be understood.

The interior of thefcap ing portion A is provided with a plura ity of cylindrical seats a, Fig. 2, corresponding in number to the number of cylinders which-theengine in-' eludes, the. part cular engine illustrated in the drawing showing four'cylinders. Placed in these seats are the cylinders B' B, which are provided with-bearing portions 7), Fig. 2, which fit snugly in said seats. The lower OItIOII of the capping portion A of the rame is formed with shoulders (1 four in number, and adjacent to the seat a. The lower end portion of each cylinder is exteriorly threaded, 'andeach threaded portion is engaged by a nut B, which bears against a washer b, interposed between the shoulder a and the upper end of the nut. Each cylinder is furthermore formed with a flange I) which. seats upon a similar flange a formed upon the upper edge of the capping portlon A, as shown in Figs. -1 and 2, whereby the cylinders and capping portion may be secured to each other in any suitable wellknown mannen That portion a of the ca ping portion A isspaced away from t e adjacent wall of the cylinden to form' a water-jacket A Fig. 2. The head of each cylinder is made of double wall construction, as shown in. Fi 2, whereby a Water-jacket is formed for t is portion of each cylinder. Cast integral with each cylinder are two valve chambers C C, of circular cross-section, and having their axes parallel with the axes of the cylinders, the one chamber acting as a valve chamber for. an inlet valve and the other as a valve chamber for the exhaust valve. Extending downwardly into these valve chambers are annular members C C, forming interior .walls and spaced away from the adjacent wall of the valve chambers so as-to form annular valve seats a c, Fig. 2. The upper ends of these members- C C are formedwithflanges 0' 0', whereby they may be rmovably secured to the main body portion of the cylinders. These flanges are formed so as to providean interior space 0 for an oil chamber, and an opening 0 is provided, to which is attached an oil duct- 0* for providing oil to this chamber. A part of the valve chamber Wall is made of double construction, so as to provide a water jacket C communicating with the water jacket ortion of the cylinder, and a suitable water inlet duct C is connected with this water jacket C Each cylinder head is rovided with an opening a, and connecte with a water outlet duct A.

ing a which-serves as an inlet and exhaust opening, as shown in Fig. 3. Each member C is provided with lateral openings 0 hori-.

zontally adjacent to the openings a in the cylinders, and above and below these openings and u on theexterior of the said members are fidrmedflgrooves' a for receiving acking rings a. Below the openings 0 and preferably formed intergral with the member C is a'transverse partition 0 whereby downward communication-with. the interior of the member G is revented.

Inlet and exhaust ucts E are secured to the to of the members 0' and communicate with the interior thereof. Seated in each of the 'valveseats c are the annular admission and exhaust valves D D. Each of these valves is provided with lateral openings d d. The lower end of each valve articulates with a connecting rod F, whose lower end is mounted upon a wrist pin 9 fixed to a crank G. .These cranks are mounted upon a valveoperating shaft G, Figs. 1 and 2. To the outer 'end \of this shaft G is secured a screw-gear g, which engages with a second screw-gear g fixed to the vertical shaft G the lower end of which latteris provided with a screw-gear g meshing with a screwgear 9 mounted upon the crank shaft Gr 'of the engine. This crank shaft is connected with the connecting rods H secured to the pistons H operating in the c linders B, as will be readily understood. T e screw gears are made of a size such that the exhaust and admission valves will-. make one complete stroke for every four complete strokes of the pistons H. The valve mechanism, together with. its cooperatingparts, forms the sub- 'ect-matter of a divisional application No.

In operation, the above described engine 'acts in the same manner as does the ordinary four=cycle type, the exhaust valve being closed when the admission valve is open.

After the admission takes place, a compression follows, and the admission valve closes,

- the exhaust valve being placed so as to be combination of a cylinder having closed at this time also. The ex losion now follows, with both exhaust an admission valves closed, and at the end of the explosion stroke of the piston H, the admission valve will have reached the uppermost limit of its'stroke. The exhaust now takes place,

withthe admission valve closed and the exhaust valve open, and followin this, the admission takes place with the-in et valve open and the exhaust valve closed, as will .be readily understood by those skilled in the art.

Having fully described my invention, what I claim therefore, and desire to secure by Letters Patent is:

1. In an internal combustion engine, the

with a valve sleeve casing and a uct extending between the cylinder and the casing, a valve slidably mounted in said casing, a water jacket casing surrounding the valve casing and aportion of the cylinder, a second water jac et casin surrounding the remainder of the cylinder, said last casing being contracted at its lower end to form a close fit with the lower portion of the c linder and being adapted to form a tight oint with said first water jacket-casing, and rin s threaded onto the cylinderfor securin tie same to the corresponding portion 0 the water jacket casing.

2.
